BEER-COOLER.

SPECIFICATION :orming part of Letters Patent No. 487,405, dated December6, 1892. Application filed February 25, 1890. $erial No. 341,771. (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, JOHN F. DUFFY, of Brooklyn, Kings county, New York,have invented a new and useful Improvement in the Distribution ofLiquids, of which the following is a full, true, and exact description,reference being had to the accompanying drawlngs.

My invention relates to a class of mechanro ism utilized on verticalcondensers, as beer and brine coolers, to effect a more evendistribution of liquid in contact with the exterior surfaces of theirpipes when condensing vapors or cooling liquids.

5 The objects of my improvement are to simplify the parts requisite forthe purpose, to expedite their attachment, to properly adjust them ifoccasion requires, to be able to replace broken or disarranged pieceswithout removzo ing heavy sections or coils of pipe, and to lessen thecost of applying the same.

Hitherto strips have been soldered to the under side of the pipes of thecoolers or condensers, requiring considerable time and the exercise ofmuch care to have them accurately placed and in line, as well as thelabor of a skilled mechanic with special appliances. Strips have alsobeen secured to the pipes by means of split rings, which encircle thepipe to which the strip is attached, being fastened thereto by havingthe ends drawn together with a screw or rivet. In either case the methodof fastening is unsatisfactory. With the flow of liquid over the pipesthere is an accumulation of scum, froth, or filth that is usuallyremoved by scrubbing the pipes and strips with a scrubbing-brush andsometimes with a metal brush. If the thin fins or strips are solderedon, they frequently become detached and broken and scatter the liquidbeing cooled or used as a cooling medium, in consequence of which thereis not only a waste of liquid, but the condensers 0r coolers become lesseffective. If the split rings are used, it necessitates the cutting outof holes in the strip immediately above the rings to permit the ends ofthe ring, which are the largest part, to pass through and encircle thepipe. They require more fitting, and the fins or strips are more readilymoved from place and get out of line when cleansed. I attain the objectby the mechanism illustrated in the accompanying drawings, in which q IFigure 1, Sheet 1, is a view of the same in elevation. Fig. 2 is asection of a strip cut to fit between pipes of a vertical cooler todistribute a moving liquid over pipes beneath it when attached to apipe, showing a notch at a, punched or cut therein to admit ofadjustment to or from a pipe when used in connection therewith. Fig. 3is an end sectional view of some of the pipes of the cooler with thereturn-bends removed to show the manner of attaching the strips to thepipes. Fig. 4:, Sheet 2-, is another-view of the invention in elevation,showing another method of applying the several parts. Fig. 5 is an endsectional view of the pipes of Fig. 4-

Similar letters aud figures refer to similar parts throughout theseveral views.

A B represent the ground-line, and C D pieces of timberupon which theframesof the cooler are mounted and to which they are bolted.

1 1 are the frames which support the vertical line of pipe 2 2 2 2, ofwhich the cooler is formed.

3 3 3 3 are return-bends into which the pipe ends are screwed to form acontinuous pas- 8o sage for gas or liquid from inlet to outlet.

4; may be the inlet and 5 the outlet, or they may be reversed.

6 is a V-shaped trough resting upon two V-shaped brackets or supportsbolted or otherwise secured upon the top of the frames 1 1. The bottomof the trough 6 is perforated to permit any liquid allowed to runtherein to leak through the perforation and trickle over the exteriorsurface of the pipes.

7 7 7 7 are strips cut of the proper width to fill the space between thepipes, or if the fit is not exact the strips are always made to touchthe pipes above them at their upper edges, as shown in Fig. 3, toprevent spattering and waste.

8 8 are clamps by which the strips 7 are fastened to the pipes 52. Theyare made to correspond with the exterior sections of the pipes, havingat each end an elongation, with Ico the inner side thereof flattened tocorrespond with other clamps of the same kind, and the surface of thestrips 7 which go between them when two clamps are used opposite to eachother on the same pipe and to which they are bolted or fastened. Theends are perforated, as at 9, to admit. a bolt or other fastening, asshown at 10. The strips 7, Figs. 1 and 3, are placed between the pipes 2and are secured thereto by the clamps 8 8, used in pairs, in which casefour pairs of clamps are made to attach two of the strips or fins inproper position with each of their upper edges against the under side ofa pipe. If they are moved from this position, the bolts may be loosenedand with a screw-driver they may be quickly replaced, the notch aadmitting of all necessary vertical adjustment.

Another method of attaching the fins or strips is shown in Figs. 1, 4,and 5, where the clamps are used singly and are made to bear against asection of each pipe, but alternately on opposite sides, thus admittingof fastening all the strips together and to the pipes, as though made inone piece, insuring strength, accuracy, and an even distribution ofliquid. The strips in Figs. 4 and 5 are capable of adjustment, asillustrated by Fig. 3. The fins or strips having been attached to thepipes of a condenser or cooler, as described, liquid is conveyed to theperforated trough b, from which it trickles through the perforations inits bottom over the pipes beneath it. The strips or fins attachedthereto and touching the under side of each pipe at its center spreadthe liquid passing over them and distribute it more uniformly on thepipes beneath.

In an application filed under even date herewith, Serial No. 341,769, Ihave shown and claimed a gutter similar to the distributer shown herein,and therefore in this application Ido not specifically or broadly claimthe distributer.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. A condenser or cooler constructed and arranged to admit of thepassage of a liquid over its exterior surface, the combination, with apipe of such condenser, of a plate, tin, or strip attached thereto byclamps or other fastenings when the said plate or fin is adjustable toor from the said pipe or another pipe in line therewith and is arrangedand operates to distribute aliquid broughtincontact with it over a pipeor pipes beneath it, substantially as described.

2. In a condenser or cooler constructed and arranged to admit of thepassage of a liquid over its exterior surface, the combination, with apipe of such condenser, of a removable and adjustable plate, fin, orstrip attached thereto by clamps or other fastenings, when the-saidplate or fin is arranged and operates to distribute a liquid brought incontact therewith over a pipe or pipes beneath it, substantially asdescribed.

3. In a condenser or cooler constructed and arranged to admit of thepassage of a liquid over its exterior surface, the combination, with apipe of such condenser or cooler and suitable fastenings, of a removableplate, fin, or strip having one or more perforations or slots that admitof its adjustment to or from the said pipe to which it is attached or ofits adjustment to or from. another pipe in line therewith when the saidplate, fin, or strip is attached by said fastenings to a pipe of suchcondenser or cooler and operates to distribute a liquid brought incontact therewith over a pipe or pipes beneath it, substantially asdescribed.

at. In a condenser or cooler constructed and arranged to admit of thepassage of a liquid over its exterior surface, the combination, with apipe of such condenser or cooler, of one or more clamps having a sectionthereof corresponding in form to the exterior of said pipe and havingtheends at right angles with the horizontal axis of the said pipe thereof,extending in opposite directions and adapted for being secured to otherclamps or other objects by bolts or other fastenings, and a plate, fin,or strip attached by said clamps and by bolts or other fastenings tosaid pipes when the said plate, fin, or strip is arranged to operate todistribute a liquid brought in contact therewith over a pipe or pipesbeneath it, substantially as described.

5. In a condenser or cooler constructed and. arranged to admit of thepassage of a liquid over its exterior surface, the combination, with apipe of such condenser or cooler, of two plates, fins, or stripsconnected therewith by clamps and bolts or other fastenings when thesaid plates, fins, or strips are arranged and operate to distribute aliquid brought in contact therewith over a pipe or pipes beneath it,substantially as described.

6. In a condenser or cooler constructed and arranged to admit of thepassage of a liquid over its exterior surface, the combination, withpipes of such condenser or cooler, of plates, fins, or strips attachedthereto by clamps and bolts or other fastenings when the said plates,fins, or strips or any of them are held in contact with said pipe andare connected together by clamps which bear against a section of pipe,but alternately on opposite sides of said pipe, and the said plates,fins, or strips or any of them are so connected and operate todistribute a liquid brought in contact therewith over the said condenseror a part thereof, substantially as described.
